HEDDLE BAR SUPPORT Filed Jan. 4, 1933 Patented Aug. 21, 1934 UNITED". S ATES I 1,971,084 r HEDDLE BAR SUPPORT Philip L Spencer, Millbury.Mass 'assignor to -.Watson-W1lliams Manufacturing Company, v Millbury, Mass., a. corporation of .Massachusetts I ApplicationJanuary 4, 1933, Serial No. 650,123- 3Claims. 401. rec-'92 This invention relates to harnesses for use in looms. In such harnesses, it is customary to provide upper and lower heddle bars on which the heddle Wires are slidably mounted, l these heddle bars being supportedat their ends in side members of the harness frame. It is also customary to provide intermediate supports for the heddle bars, particularly if the harnesses are of substantial width.

It is the general object of my invention to provide an improved intermediate heddle bar support by which a heddle bar may be easily secured or released and by which it will be firmly held during the operation of the loom.

I further provide a heddle bar support which is simple in construction, economical in manufacture and fully reliable in use.

My invention further relates to arrangements and combinations of parts which will be here- 16 inafter described and more particularly pointed out in the appended claims.

A preferred form of the invention is shown in the drawing, in which Fig. 1 is a front elevation of a loom harness embodying my improvements;

Fig. 2 is an enlarged detail front elevation of my improved heddle bar support, with a portion of the harness frame shown in section;

Fig. 3 is a side elevation, looking in the di- 10' rection of the arrow 3 in Fig. 2;

Figs. 4 and 5 are views similarto Figs. 2 and 3 but showing the locking member in released position;

Fig. 6 is a plan view of the locking member;

.36 Fig. 7 is an enlarged detail view, looking in the direction of the arrow 7 in Fig. 6, and

Fig. 8 is a side elevation of a double heddle bar support.

Referring to the drawing, I have shown a 40 loom harness comprising top and bottom frame members 10 and 11, side members 12, and upper and lower heddle bars 13 and 14 on which wire heddles' H are slidably mounted. The ends of the heddle bars. 13 and 14 extend through the 45 side members 12 and are suitably secured therein by any convenient locking means.

The parts thus far described may be of any usual construction and in themselves form no part of my present invention which relates par- 80 ticularly to the intermediate heddle bar supports shown in detail in Figs. 2 to 8.

Referring particularly to Figs. 2 and 3, my improved heddle bar support comprises a post having a threaded portion 21 adapted to be 66- screwed into and supported by one of the harness frame .members 10 or '11.. The post 20 at its outer end is preferably of flattened cross section and is provided with a recess 22 (Fig. 5) having an offset notch 23. The recess 22 is made of such width as to conveniently receive one of the heddle bars 13 or 14, the bar being inserted by a simple sidewise movement.

I also provide a locking member for each post 20, the member 30 being preferably formed from a single piece of sheet spring steel or other suitable resilient metal.

Each locking member 30 comprises a sleeve portion 31 loosely fitting the post 20 and a U- shaped spring portion 32 having a reduced end portion 33 adapted to be inserted in-an opening 34 in the post 20. The end portion 33 is preferably formed by folding over the edges of the end portion of the spring 32, as clearly indicated in Figs. 6 and 7. The sleeve portion 31 is provided with end notches 36 adapted to receive one edge of a heddle bar 13 or 14. Each post 20 and locking member 30 are assembled as shown in Fig. 2

When a heddle bar is to be inserted, pressure is applied, to the spring 32 in the direction of the arrow a in Fig. 4. The sleeve 31 is thus easily moved to the position shown in Figs. 4 and 5, clearing the recess 22 so that a heddle bar may be easily inserted sideways therein. The locking member 30 is then released, moving to the position shown in Figs. 2 and 3, and the heddle bar is firmly seated in the notches 23 and 36, thus preventing displacement of the bar.

My improved heddle bar support is thus extremely simple in construction and'operation, 9 and is very easily and economically manufactured in quantity.

Under some conditions it is desirable to use two upper and two lower heddle bars, in which case the double support shown in Fig. 8 will be provided. The construction is the same as previously described, with the exception that the post is increased in widthto provide two recesses 51 and two notches 53, and the locking member is also of increased width and is provided with two notches 61, one for each of the two heddle bars. Otherwise the construction and operation is the same as for a single support.

It will be noted that the locking member in my improved support may be very conveniently operated by inserting a finger under the spring 32, leaving the other hand entirely free to manipulate the heddle bar. It will be further noted that I use a single moving part only, which said post and engaging an edge of said bar, said member having a U-shaped spring formed integral therewith and projecting laterally therefrom, with the free end of said spring, extending toward said post and insertable in anopening in said post when the parts are assembled.

2. A heddle bar support comprising a postr having a recess open at the side to receive a heddle bar, and a locking memberslidably mounted on said post and notched toengage an edge of said bar, said member having a U-shaped spring formed integral therewith and projecting laterally therefrom, with, the free end of said spring extending toward said post and with the edge portions of the free end of said spring folded to provide a reduced end portion insertable in an opening in said post when the parts are assembled.

3.YA ,heddle bar support comprising a post having a recess open at the side to receive a heddle bar, and a locking member slidably mounted on said post and engaging an edge of said bar, said member being formed from a single piece of resilient sheet metal and comprisinga sleeve portion embracing said post and a U-shaped spring portion formed integral with saidsleeve portion and projecting laterally from an edge of said sleeve portion and having its free end extending toward said post and insertable in an opening in said post when the parts I are assembled.
